Engine: B5244: Odd vibration at startup

[tim2001]

Hi everyone, before I start, I want to thank all contributors to this forum as it has been a little goldmine of information for me over the many years of Volvo ownership.
I have an '02 V70 Petrol, just passed the 210k and most work and service I manage myself. Recently I have noticed a strange vibration after ignition, the weird thing is, I cannot hear it under the hood, only when I'm sat inside the vehicle.
I just cannot work out what it is and it seems to disappear after a few minutes of driving. I read on the US forum that it may be the mesh surrounding the down pipe to the exhaust, but I checked that and it seems okay.

Can anyone shed any light on this bizarre noise?

Many thanks

Have you checked the top engine mount

[tim2001]

Thanks, I've not no, what should I look for? Last time I checked it was about a year ago, I'll go check it right now. Thanks again.

its where the bar attaches to the mount, which runs across the top of the engine like a strut brace

[tim2001]

Yep, hehe, I know which it is, I meant what should I look for, the rubber looks okay, not cracking nor deteriorated, would I need to jack the block from underneath to pull it apart and closely examine it?

Me again, I've just been out again, asked the wife to startup and had a really close inspection. You're a legend! It's torn right under the lip, not visible unless I stuck my thumb right in there and it actually slides about .5cm each way with some manipulation.
Do you think that would be it?

There's another torque mount with perishable bushes underneath the engine/gearbox joining it to the subframe so check that too.

Thanks gents, much appreciated, I'll have good look and jack the engine so I can get a better look them all.

Use the side jacking points or the subframe to lift the car.
Don't jack the engine whatever you do. .

I've got a couple of axle stands, just reading the Haynes bible, it mentions a couple more mounts, I think I'll check them all, this might come up trumps
